Events

Events are, admittedly, a little confusing. To help alleviate this confusion, keep the following in mind when working with events:

Events can be either one-time events or recurring.
Events can have a specific start and end time or last all day. The values of the start and end properties will depend on whether the event has a specific start and end time or lasts all day.

Get a collection

      Endpoint
    
GET /events HTTP/1.1

Query string parameters

All query string parameters are optional.

callback string

Wraps the response in a callback function of the given name. Use this parameter to facilitate JSONP requests.

channels comma-separated list of IDs

Return events assigned to the given channels.

date string

Return events that take place on a specific date or within a date range. If specifying a range, separate start and end dates with a comma.

Return events assigned to the given event categories.

excluded_ids comma-separated list of IDs

Returns events, except those with the given IDs.

ids comma-separated list of IDs

Return events with the given IDs.

include_subterms comma-separated list of IDs

Works in conjunction with hierarchical taxonomy parameters to ensure returned events are assigned to either the specified term(s) or the children of the specified term(s). Hierarchical taxonomy parameter(s) available on events: event categories and locations

For example, /events?locations=668&include_subterms=668 will return events assigned to term #668 (Homewood Campus) and any other location whose parent is Homewood Campus.

locations comma-separated list of IDs

Return events assigned to the given locations.

open_to comma-separated list

Return events that may be attended by the given audience(s). Options: faulty, staff, students, everyone

Default value: everyone

order_by comma-separated list

Sort events by one or more ORDER_BY and ORDER parameter pairs. Options:

ORDER:
- asc: order from lowest to highest values
- desc: order from highest to lowest values
ORDER_BY:
- id: order by event ID
- list: order by the order of IDs given in the ids parameter
- publish_date: order by publish date
- score: order by popularity
- start_date: order by the starting date

Format: ORDER_BY|ORDER[,ORDER_BY|ORDER,...]

Default value: start_date|asc,id|asc

page integer

Return events from a specific page of a collection.

Default value: 1

per_page integer

Number of events to return per page of a collection. Maximum: 100

single_events boolean

When true, recurring events are expanded into individual event objects. For example, an event that recurs 10 times will be represented with 10 separate objects in the event collection.

When false, recurring events are returned as a single event object. For example, an event that recurs 10 times will be represented with 1 object in the event collection. Inspect _embedded.event_instances for a list of all instances of the event.

Default value: true

source comma-separated list

Return events published by the specified source(s). Options:

all: returns all events in the database.
hub: returns only events published to the Hub calendar. Events excluded from the Hub calendar consist mostly of HR-related events.
